Investigation of Adding Microscopic Slide Glass Nano Particles on the Metallurgical Characterization and Mechanical Properties of Cast Aluminum 7075 Composites

Metal Matrix Composite (MCC) exhibits significantly better properties, like hardness, high tensile strength, low density, and good wear resistance compared to alloy or any other metals. In the present study, the effect of using different proportions (2, 4, 8 and 10 wt.%) of microscopic slide glass nano particles (MSGNP) on the properties of Al-7075 alloy was investigated. The results of the experimental investigation of the metallurgical characterization and mechanical properties of aluminum MMC that formed by stir casting were obtained. Stir casting is the process of introducing a reinforcing material into a molten metal by stirring it in. The results of the aluminum MMC were compared with those for the base alloy material. Optical microscopy, scanning electron microscope (SEM), energy dispersive spectroscopy (EDX), and X-Ray Diffraction study (XRD) were carried out to analyze the microstructure and the dispersion of the (MSGNP) into the composite alloy specimens. Regarding the mechanical properties, the Rockwell hardness gradually increased when the addition of MSGNP was raised from 0 to 10wt.%. Also, there was an increase in the ultimate tensile strength, peaking at the incorporation rate of 4wt.% MSGNP and thereafter, this strength deteriorated. Therefore, the addition of microscopic slide glass nano particles to the Al-7075 is good for enhancing the alloy properties for engineering application.
